Title: Vehicle-to-vehicle distance warning device
Inventor: IOHARA KENJIRO
IPC: G01S17/42
Filed: 1994-12-08
Abstract: PURPOSE: To secure the safe traveling of a vehicle by making the vehicle issue a warning to the succeeding vehicle in accordance with the degree of risk of accident that the vehicle might have in front of the vehicle so that the driver of the succeeding vehicle can be informed of the degree of risk. CONSTITUTION: A range finder 21 emits a light beam S1 against a preceding vehicle, measures the distance to the preceding vehicle from the vehicle from the arrival time of the reflected light beam S2 from the preceding vehicle, and outputs distance information S5. A relative speed computing element 22 computes the relative speed S6 between the vehicle and the preceding vehicle from the distance information S5 and the measured time interval. A car speed measuring instrument 23 measures the traveling speed S7 of the vehicle and a safe vehicle-to-vehicle distance computing element 24 computes the safe vehicle-to-vehicle distance S8 to the preceding vehicle from the speeds S6 and S7. A degree-of-risk calculating device 25 calculates the degree of risk between the vehicle and the preceding vehicle from the information S5 and distance S8 and outputs a danger signal S9. When the danger signal S9 is outputted, a warning generator 26 issues an acoustic warning S3 to the vehicle and a succeeding-vehicle warning generator 27 issues an acoustic or optical warning S4 to the succeeding vehicle. Therefore, the succeeding vehicle can recognize the degree of risk concerning the preceding vehicle.

IPC: G01N21/84
Filed: 1986-12-24
Abstract: PURPOSE:To obtain an optical fiber sensor with good temperature stability by propagating incident light along two different axes by equal length until projection. CONSTITUTION:Polarized wave maintenance type optical fibers 1 and 2 of the same length are connected at a connection point 3 while rotated by 90 deg. mutually on their center axes so that the direction of the optical fiber 1 shown by an arrow A and the direction of the fiber 2 shown by an arrow B meet each other.

External pressure to be detected is applied to the fibers 1 and 2 through a pressure receiving plate. The directions of application to the fibers 1 and 2 are both coincident with the direction of the polarized component C. Light from a light source 6 is polarized and incident on the fiber 1 at 45 deg. to the arrows A and B. In this case, the polarized component C shown by the arrow A and the polarized component D shown by the arrow B are equal in quantity. Further, the phase difference between the polarized components C and D is detected by a photodetector 8 while the polarizing direction of a polarizer 7 is set at the light projection part of the fiber 2 at 45 deg. to the arrows A and B.

Title: Developing device
Inventor: KURITA TAKAHARU
IPC: G03G15/06
Filed: 1987-12-02
Abstract: PURPOSE:To eliminate an increase of fog, adhesion of a carrier, a stripe and a blur, and also, to improve the reproducibility of a horizontal fine line by providing a difference of a developing bias to a photosensitive body between a part where the surface of a developing roller approaches the photosensitive body and a part where said surface is separated from the photosensitive body. CONSTITUTION:As a developing roller 3 rotates, each very small electrode 6 rotates and comes into contact with a slide-rub brush 12a of the upstream side and a potential E1 is applied, and further rotates and comes into contact with a slide-rub brush 12b of the downstream side and a voltage E2 is applied, and the very small electrode part having a prescribed position relation against a photosensitive body 100 always becomes a prescribed potential. That is, in a position where a contact of a developer starts against the photosensitive body surface 100, the applied bias is weakened and a sufficient toner is supplied to the photosensitive body surface, and on the other hand, in a position where the developer surface is separated from the photosensitive body, a strong bias is applied and an unnecessary toner is eliminated entirely from the photosensitive body surface. In such a way, the directional property of an edge effect at the time of development and the reproducibility of a horizontal fine line are improved, and the image density is improved.

Abstract: PURPOSE:To improve the operational property by controlling either a mechanical observation image moving device or an electrical observation image moving device with a common device selectively. CONSTITUTION:By operating an X direction regulation knob 11X and a Y direction regulation knob 11Y, a computation processor 10 reads the present specific magnification from a magnification converter 12, and when it is less than 100,000 times, a mechanical observation image moving device is selected, a moving signal is output to D/A converters 9-1, and 9-2, and straight advance motors 3X and 3Y are moved forward or backward to move a sample in the X and Y directions. When the magnification is 100,000 times or higher, an electrical observation image moving device is selected, image shift-control coils 5X and 5Y are excited by D/A converters 9-3 and 9-4, and the position of the observation image on a fluorescent plate is moved. Since the computation processor 10 is reading the specific magnification constantly, the moving device responding to designated magnification can be selected automatically instantly even though the magnification is converted. Consequently, the operational property of the observation image moving is improved, and the accurate observation image movement can be carried out.

Abstract: PURPOSE:To reduce the disconnection of wire at the time of chamfering by providing a means for changing the processing condition at the time of start of the processing to the main processing condition step by step. CONSTITUTION:In the case where the processing condition setting command is read out from a memory 2, the command is sent to a processing condition command analyzing device 4.

On the other hand, the processing condition command from a NC data reading and analyzing device 3 and the processing condition command read from the memory 11 are sent to a processing condition control device 12. The processing condition control device 12 sends out the processing condition, which is changed step by step, to the power source control device 6, to indicate a change of the power source notch. Smooth movement from the entrance processing to the main processing step by step is thereby performed by changing the power source notch.
